UPDATE: The Ameritex fire has reached 100 percent containment. However, local fire departments will continue to monitor the fire for the next few days. A structure fire quickly turned into a wildfire in just off Highway 90 in Seguin, Guadalupe County. Firefighters were called to the structure fire, which quickly spread to a barn, then ignited four small wildfires. The 5-10 mile-per-hour southerly winds then caused the four smaller fires to become a 30-acre fire. Texas A&M Forest Service was dispatched at 1549 and worked in a unified command with Guadalupe County Fire Department. Priority was given to protecting between 20-30 homes which were threatened, while TAMFS deployed two dozers and a Type 3 Engine. The dozers worked to construct fire containment lines through heavy brush on the east and west flanks, while fire apparatus from Geronimo Volunteer Fire Department, South Hays VFD, New Braunfels VFD, City of Seguin VFD, Schertz VFD, Lake McQueeney VFD, and Kingsbury worked to...

1212 PM CDT Fri Jul 29 2022
Valid 301200Z - 311200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms associated with strong winds will be possible on
Saturday afternoon from parts of Oklahoma and far northeast Texas
into Arkansas.
...Synopsis and Discussion...
Expansive subtropical ridging is forecast to extend across the
Southeast and southern Plains early Saturday morning, with another
upper ridge centered near the northern CA/NV and covering much of
the western CONUS. This dominance of upper ridging will lead to
predominantly weak flow aloft across the majority of the CONUS. The
only exceptions are early in the period across the Northeast, before
the shortwave trough extended over the region moves eastward, and
over the northern High Plains/northern Plains during from late
Saturday afternoon into Sunday morning. This second area will be
coincident with a modest shortwave trough moving through the
Canadian Prairie Provinces and adjacent northern High
Plains/northern Plains.
Surface pattern is expected to feature a large ridge centered over
the OH Valley, and modest lee troughing across the High Plains. A
frontal zone will exist between the more continental air associated
with the ridging and moist air mass across much of the southern
Plains and Southeast. This frontal zone will be fairly broad, with
some more defined portions possible due to potential augmentation
via thunderstorm outflow, and is expected to act as the corridor for
additional thunderstorms development during the afternoon and
evening.
Weakly sheared nature of the environment suggests a predominantly
multicellular mode with limited updraft strength and duration. Given
the very moist character of the air mass (i.e. PW values of
2-2.25"), a few isolated water-loaded downbursts capable of damaging
wind gusts could occur. However, widely spaced character of events
and overall marginal nature of the threat merits keeping severe wind
probabilities below 5% for this outlook.

.PREV DISCUSSION... /ISSUED 0200 AM CDT Fri Jul 29 2022/
...Synopsis...
A large-scale ridge will remain centered over the western CONUS,
while a low-amplitude shortwave trough tracks southeastward across
the northern Rockies. Beneath the upper ridge, hot/dry conditions
will result in widespread 10-15 percent minimum RH east of the
Cascades into the northern Rockies. The low RH, coupled with breezy
northerly surface winds over southeast OR, southwest ID, and
northern NV will promote elevated fire-weather conditions during the
afternoon -- especially owing to highly receptive fuels over the
area.
In addition, large-scale ascent ahead of the shortwave trough and
favorable midlevel moisture/instability will support isolated to
widely scattered high-based thunderstorms over the northern Rockies.
As these storms overspread a hot/dry boundary layer and critically
dry fuels, lightning-induced ignitions will be possible. Farther
west, upslope flow and adequate instability will also support very
isolated high-based thunderstorms along the Cascades in northern CA
into southern OR -- where isolated ignitions remain a concern.

MD 1610 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL/EASTERN VIRGINIA TO EASTERN MARYLAND/SOUTHERN DELAWARE
Mesoscale Discussion 1610
NWS Storm Prediction Center Norman OK
1124 AM CDT Fri Jul 29 2022
Areas affected...Central/eastern Virginia to eastern
Maryland/southern Delaware
Concerning...Severe potential...Watch possible
Valid 291624Z - 291830Z
Probability of Watch Issuance...60 percent
SUMMARY...Thunderstorms are expected to develop/increase this
afternoon initially across Virginia near the Blue Ridge and spread
eastward toward/across the Chesapeake bay vicinity. Isolated wind
damage may occur with the strongest storms. Trends are being
monitored for a possible Severe Thunderstorm Watch.
DISCUSSION...Strong heating and ample insolation/boundary layer
destabilization are occurring across the southern half of Virginia
to the south of a southwest/northeast-oriented effective front from
the central Appalachians toward the Delmarva, although buoyancy will
be somewhat tempered by warm mid-level temperatures (-4 to -5C at
500mb) and poor mid-level lapse rates. Regardless, thunderstorms
will develop and increase through mid-afternoon over the mountains
and Blue Ridge vicinity and subsequently spread eastward.
Influenced by the upper trough over the Great Lakes, a belt of
moderately strong westerlies is noted, particularly with northward
extent near/north of the frontal zone. This will support sustained
multicells/linear segments as thunderstorms develop, and possibly
even some transient supercells across east-central Virginia/eastern
Maryland and Chesapeake Bay vicinity. A very moist boundary layer
and steepening low-level lapse rates could yield some downbursts
capable of isolated wind damage as the most probable severe hazard.

1108 AM CDT Fri Jul 29 2022
Valid 291630Z - 301200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS VA AND CHESAPEAKE
BAY VICINITY...
...SUMMARY...
Potential for scattered damaging winds from strong to locally severe
gusts is greatest across parts of Virginia and the Chesapeake Bay
vicinity through early evening.
...VA and Chesapeake Bay vicinity...
South of a slow-moving surface cold front, a southwest to
northeast-oriented zone of differential boundary-layer heating is
apparent from southwest VA to the Chesapeake. Scattered
thunderstorms are expected to develop along this corridor through
the afternoon. On the fringe of 35-40 kt mid-level westerlies in
conjunction with a pronounced buoyancy gradient, a mix of multicell
clusters and transient supercell structures are anticipated. Amid
weak mid-level lapse rates, strong to locally severe gusts producing
mainly tree damage should be the primary threat into early evening.
...Southern Appalachians to the Mid-South...
Scattered thunderstorms are again expected along the composite
outflow/differential heating corridors south of the quasi-stationary
surface front. Isolated strong/damaging downbursts will be possible
with water-loaded downdrafts on the fringe of modest mid-level
westerlies.
...Red River Valley and TX Panhandle...
Isolated to scattered thunderstorms are expected from late afternoon
into mid-evening both along the surface cold front near the Red
River and in a post-frontal regime over the TX Panhandle. Deep-layer
shear will be weak across the region, especially for convection
along the front. The latter will be compensated by a deeply mixed
thermodynamic profile with hot temperatures south of the front.
Isolated strong/damaging downbursts will be possible with
water-loaded downdrafts. Farther west, slow-moving cells/clusters
may contain a threat of both isolated, marginally severe wind/hail.
...Southern Great Basin...
Around the southeast periphery of a mid-level anticyclone centered
over northern CA, modest northeasterly flow of 15-20 kt will be
maintained over southern NV. Boundary-layer dewpoints are generally
in the low to mid 60s this morning and gradual clearing of clouds
will allow strong surface heating this afternoon with MLCAPE
increasing to 500-1500 J/kg. Isolated to scattered thunderstorms are
expected to form by late afternoon close to the NV/UT border, and
storms will subsequently spread south-southwestward on outflow into
southern NV and adjacent areas of southeast CA. Given the modest
buoyancy and steep low-level lapse rates, isolated severe outflow
gusts up to around 70 mph will be possible with multicell clusters.
...Northern MT...
A low-amplitude shortwave impulse over southeast BC will drift east
across southern AB. Though moisture will be limited, deep
boundary-layer mixing will occur as surface temperatures warm
through the 90s. Weak ascent preceding the upper trough and weak
low-level convergence along a surface trough will support isolated
to scattered thunderstorms later this afternoon. Though low to
mid-level flow will remain weak, deep inverted-v profiles will favor
isolated strong outflow gusts of 50-60 mph.
...NE Panhandle vicinity...
Isolated thunderstorms may develop along the northern periphery of
the High Plains moisture plume during the late afternoon/early
evening. Adequate veering of the wind profile with height (weak
low-level southerlies to modest mid-level northwesterlies) will
support a short-duration and very isolated threat for marginally
severe hail/wind.

The Long Creek Fire began at about 1245pm on Wednesday, July 27. The fire began due to a spark created by fire equipment. By 4pm the fire had grown to about 150 acres with 0% containment. The fire had a very high potential for growth and was burning in thick brush. There was no threat to structures. Dozers finished constructing line along the fire's perimeter at around 630pm. At that time, the fire was estimated to be 215 acres in size and 50% contained. Engines continued to mop up residual heat along the fire's perimeter until the fire was determined to be 90% contained. Fire crews will return Thursday morning to patrol the fire area and mop up any residual heat along the fire's

Tropical Storm Georgette Discussion Number 9
NWS National Hurricane Center Miami FL EP082022
800 AM PDT Fri Jul 29 2022
GOES-17 Proxy-Vis and enhanced IR imagery show that Georgette's
cloud pattern has become more symmetric with colder -77C inner core
cloud tops. An earlier AMSR2 revealed an eye-like feature in the
lower frequency band and a well-developed rain band in the north
part of the cyclone. The eye feature, however, was not evident in
the infrared presentation. Although the Dvorak subjective
T-numbers from TAFB and SAB haven't changed; the initial intensity
is increased to 50 kt in deference to the microwave image.
The global models and the statistical intensity guidance indicate
that the easterly shear will increase within 24 hours, causing
Georgette to weaken slowly. However, due to Georgette's compact
size, intensity fluctuations are possible in the short term. The
latest GFS run shows that Georgette could hang on a little longer
than the NHC forecast indicates, possibly as a post-tropical
cyclone. Therefore, adjusting the forecast may be deemed necessary
to extend the cyclone's life in subsequent advisories. The official
forecast is very close to the HCCA and IVCN intensity aids.
Georgette's initial motion is estimated to be just a bit south of
due west or 260/11 kt. A mid-tropospheric ridge stretching
east-northeast to west-southwest should steer the small cyclone
west to west-southwestward during the next 48 hours. Afterward, a
reduction in forward speed along with a turn toward the northeast
is expected in response to larger Frank weakening the ridge and
disrupting the steering flow while passing to the northeast of
Georgette. Although the ECMWF global has been the best performer
in the eastern Pacific this season with respect to forecast track,
the model continues to initialize poorly the compact TC indicating
a significantly weaker system while remaining the left tracker
outlier. The GFS, however, now has a more accurate depiction of
the cyclone's size and vertical depth and shows a more direct
response to Frank's larger wind field. There still is quite a bit
of uncertainty in Georgette's future track as evident by the larger
than usual guidance spread, particularly after the northeast turn.
Consequently, this is a low confidence forecast. The NHC forecast
is similar to the previous advisory through 48 hours, but has been
adjusted to the left beyond that point to agree more with the HCCA
and GEFS/EPS ensemble member solutions.

Tropical Storm Frank Discussion Number 14
NWS National Hurricane Center Miami FL EP072022
900 AM MDT Fri Jul 29 2022
In infrared imagery, Frank's appearance has not changed much since
the last advisory. While the system shows a large curved
convective band that wraps a little more than three-quarters of the
way around the center, the central deep convection is a bit ragged,
possibly due to dry air entrainment from the northwest. However,
recent 37 GHz microwave data shows the cyclone has developed a
good low-level structure, with a ring of shallow to moderate
convection surrounding a 40 n mi wide developing eye. Satellite
intensity estimates have changed little since the previous
advisory, so the initial intensity remains 55 kt.
Frank will be in an environment of light vertical shear and over
sea surface temperatures of 28-29C for the next 36 h, and the
inner-core structure seen in the microwave imagery favors a faster
rate of strengthening. The one current negative factor is the dry
air entrainment that is causing the inner core deep convection to
sputter. The intensity forecast assumes strengthening will resume
as the deep convection will becomes persistent, and it follows the
trend of the intensity guidance in calling for a peak intensity of
90 kt in 36 h. After that time, Frank should move over
progressively cooler SSTs, with the system reaching 21C water by
120 h. This should cause steady to rapid weakening, and Frank is
forecast to become a remnant low by the end of the forecast period.
The initial motion is now 300/10 kt. Frank is moving along the
southwest side of the subtropical ridge over northwestern Mexico,
and it should move generally northwestward during the forecast
period toward a developing break in the ridge west of California.
The track guidance is in good agreement with this scenario and has
changed little since the previous advisory. Thus, the new forecast
track is an update of the previous forecast.
It again should be noted that Frank and Tropical Storm Georgette
are expected to come close enough to one another for some
interaction. Frank will be the larger and dominant system during
this interaction, and Georgette will have little impact on the track
or intensity of Frank.
